Wizards of the Coast released a new clue as to the what cards will be featured in the next Secret Lair: Drop Series release, which will likely be Strixhaven: School of Mages-themed.
It has been a few months since WotC previewed a Secret Lair drop (see “Wizards of the Coast Unveils ‘Magic: The Gathering’ ‘Secret Lair: Smitten Superdrop'”). With the pending release of the new Strixhaven: School of Mages set on the horizon (see “Wizards of the Coast Updates Release Information for ‘Magic: The Gathering’ ‘Strixhaven: School of Mages’ “), WotC released a tweet through their Secret Lair twitter feed with a photo that provides some clues to the nature of the next drop. The photo depicts the upper half of a bookcase from the Secretorium with four unrevealed cards on the top shelf that will be included in this Strixhaven-themed release.
Underneath the top shelf, there are items that likely provide clues to which four cards will be included. Twitter user speculation as to the identity of these cards, based on the clues, include Scroll Rack, AEther Vial, Baleful Strix, Springleaf Drum, and others.
